Answers
Answer:
1)Bangalore is known as the Silicon Valley of India because of its role as the nation's leading information technology (IT) exporter. It is called so due to any number of startups coming up in the city. The city is situated on the Mysore plateau and the area is often referred to as silicon plateau.
2)Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn't react with kerosene.
White phosphorus is highly reactive, and spontaneously ignites at about 30°C in moist air. It is usually stored under water, to prevent exposure to the air. It is also extremely toxic, even in very small quantities.
